From the sites I took a look at (where folks have posted results), for the most part standard Zip might give you about 10-15% compression at most (although Zipx format could give you 30-ish%; RAR is up around 30-35%, but FLAC (which is optimized for compressing audio specifically) will generally give you 40-50% compression on WAV files. Your results, of course, will vary depending upon the size of the files and he content of the files.
